Usage: php update-icu-component.php <path/to/icu/source> <path/to/icu/build>

Updates the ICU data for Symfony2 to the latest version of the ICU version
included in the intl extension. For example, if your intl extension includes
ICU 4.8, the script will download the latest data available for ICU 4.8.

If you downloaded the SVN repository before, you can pass the path to the
repository source in the first optional argument.

If you also built the repository before, you can pass the directory where that
build is stored in the second parameter. The build directory needs to contain
the subdirectories bin/ and lib/.

For running this script, the intl extension must be loaded and all vendors
must have been installed through composer:

    composer install --dev
